Where in manual is de-plating?

I can't seem to find de-plating procedure..

Hello,

I have stripping nickel from brass/bronze for over 25 years.
Stripping nickel can be done two ways:
1. Chemically by purchasing Caswell immersion nickel strippers.
2. Perform chemically with reverse current (anodic) to removel plated nickel.

Care must be taken because the nickel layer changes in thickness due to current densities (low, mid, high current densities). Nickel thickness follows the low current density- lowest nickel thickness, etc..
Inaddition, you need to remove all nickel deposit before replating.
After stripping nickel clean and polish. If you see nickel restrip nickel becasue if you try to buff it off you will be removing brass material.

I recommend Caswell nickel strippers because they are proven product.
Stripping plating is much harder than plating.
Good Luck,

NOL4154,

You really must need something to do, do you realize your responding to a five year old post?
